To troubleshoot why your network connection drops when using a certain device, it is suggested that you:

1. Check your router. Make sure it is securely connected to the wall. If it is plugged in, it would be beneficial to power cycle the router.
2. Check your device. Make sure the connections are secure and the device is powered on.
3. Check that the correct network is being used. It is possible the correct network is not being used, and instead, another is being used by the device.
4. New device setup. Make sure the device was properly setup before connecting and re-verify the settings.
